Detailed Description

A compiled daslang program ready to run.

Reused across many evaluations so the cost of compiling is paid once. Each eval helper runs an exported function by name and returns its result.

Example

String error;
auto script = DasRuntime::instance().compile("expr", source, error);
floatT result = 0;
script->evalFloat("__eval__", result, error);

Note

daslang types stay inside the implementation so consumers never include daslang headers.

Member Function Documentation

evalFloat()

bool enzo::expr::CompiledScript::evalFloat	(	const String &	functionName,
		const ExpressionContext *	context,
		floatT &	result,
		String &	error )

Evaluates an exported function as a float.

Returns

True on success, false when the function is missing or panics.

evalInt()

bool enzo::expr::CompiledScript::evalInt	(	const String &	functionName,
		const ExpressionContext *	context,
		intT &	result,
		String &	error )

Evaluates an exported function as an integer.

Returns

True on success, false when the function is missing or panics.

evalString()

bool enzo::expr::CompiledScript::evalString	(	const String &	functionName,
		const ExpressionContext *	context,
		String &	result,
		String &	error )

Evaluates an exported function as a string.

Returns

True on success, false when the function is missing or panics.
